If you have basic understanding of problem solving skills you can easily clear this test. 2. Technical Interview: This is the best technical interview that I ever faced in my career till now. He is very polite and explaining the situation very well. First he introduced himself and basic information regarding the roles and responsibility. He literally grilled me for various ML concepts, statistics behind few algorithms like Random Forest, logistic regression and NLP. As I already having working experience on various ML techniques, I answered almost all of the questions. 3. Business Interview: She took my interview in Fractal office Bangalore. She is very humble. Initially I was little bit nervous but she helped me to feel normal. After casual discussion, she gave me a case study of one application.
